“While used every day, the term “security” can be deceptively difficult to define and may contain various meanings to different people in divergent contexts. The industry at large seems to have adopted a stance of “I know it when I see it,” as opposed to objectively defining the concept. Unfortunately, this creates numerous problems for those who have a need to ‘secure’ data, or any other asset.
For more than two decades, I have served in a number of security functions, and have found it curious that in each industry or domain few, if any, people were able to provide a clear definition of the term ‘security’.

They are concepts that are critical in the fields of information security, risk management and other areas of security. In truth, the concepts extend beyond IS but they are very common in the IS World and easier, in my opinion, to discuss in the context of IS. So what are exploits & vulnerabilities and why are they important?
First, we need to understand that there is no “guaranteed security” and security can never be 100% as there are always vulnerabilities which can be exploited. We may not have identified them yet, but they do exist. Given enough time, effort, and the right tools, any security control can be circumvented. Security should be viewed as a function of time and effort. (this will be discussed below) Second it is important to understand that the concepts of exploits and vulnerabilities are inextricably entwined and are mutually dependent. This is where the debate begins so first lets get a working definition of the terms. Continue reading
